we have autumn raseberrys, cant remember the name of them and Him In Doors - who comes out to tend his raspberrys - cuts them down to the ground when all the fruit has done. We started with 10 plants and last spring had too cut off and dig up all the extra plants that had grown from the main plants. We ended up giving them away.
the fruit is so sweet and there is always plenty for jam, smoothies, ice cream raspeberry muffins etc etc etc!
